On a modern game with no upper playfield, the needs of the shooter lane, how it typically joins up with the orbit, and how it pushes the natural flipper position to the centre of the apron, a little left from the centre of the playfield, makes it easier to place a cross-field shot flipper on the right side than the left, placed below the join point of the shooter lane.

A game with a cross-playfield plunge from the shooter lane all but guarantees an extra such flipper would be placed on the right.

A game with an extra inlane offsetting the flipper position is more likely to put the upper flipper on the same side; the orbit return is more oblique and the flipper is allowed to aim further upward. The exception to this is if a shot through the pops lower down the field is present, as that will be what pushes EVERYTHING further to the opposite side as well as the most space to design a loop entry being above the pops.
